FIG. 2 is an enlarged, fragmentary developmental plan view of the tread and buttress of FIG. 1;

FIG. 3 is an enlarged sectional view of the tread and buttress, taken substantially as indicated by line 3--3 of FIG. 2; and

FIG. 4 is an enlarged sectional view of the tread buttress, taken substantially as indicated by line 4--4 of FIG. 2.
